FS#15311 — ldn-5-a9 / ldn-5-n7

Details
We will upgrade those equipment in the latest versions recommended:
> ldn-5-a9
> ldn-5-n7

The objective on the n77 is to allow the implementation of new features and new hardware support during the coming next year on this equipment. On the ASR9k, the objective is to fix the bug on the NP of the linecards.

Both equipment will be isolated before maintenance, and traffic will flow to other peering points.

We plan to do this maintenance on Wednesday 22nd of February at 00:00 (UTC).
